RTL-SDR is an affordable dongle that can be used as a computer-based radio scanner for receiving live radio signals between 500 kHz and 1.75 GHz in your area. The RTL-SDR V4 offers several improvements over generic brands including use of the R828D tuner chip, triplexed input filter, notch filter, improved component tolerances, a 1 PPM temperature compensated oscillator (TCXO), SMA F connector, aluminium case with passive cooling, bias tee circuit, improved power supply, and a built in HF upconverter. RTL-SDR V4 comes with the portable dipole antenna kit. It is great for beginners as it allows for terrestrial and satellite reception and easy to mount outdoors and designed for portable and temporary outside usage. Features Improved HF reception: V4 now uses a built-in upconverter instead of using a direct sampling circuit. This means no more Nyquist folding of signals around 14.4 MHz, improved sensitivity, and adjustable gain on HF. Like the V3, the lower tuning range remains at 500 kHz and very strong reception may still require front end attenuation/filtering. Improved filtering: The V4 makes use of the R828D tuner chip, which has three inputs. The SMA input has been triplexed input into 3 bands: HF, VHF and UHF. This provides some isolation between the 3 bands, meaning out of band interference from strong broadcast stations is less likely to cause desensitization or imaging. Improved filtering x2: In addition to the triplexing, the open drain pin on the R828D can be also used, which allows to add simple notch filters for common interference bands such as broadcast AM, broadcast FM and the DAB bands. These only attenuate by a few dB, but may still help. Improved phase noise on strong signals: Due to an improved power supply design, phase noise from power supply noise has been significantly reduced. Less heat: Another advantage of the improved power supply is low power consumption and less heat generation compared to the V3. Included 1x RTL-SDR V4 dongle (R828D RTL2832U 1PPM TCXO SMA) 2x 23 cm to 1 m telescopic antenna 2x 5 cm to 13 cm telescopic antenna 1x Dipole antenna base with 60 cm RG174 1x 3 m RG174 extension cable 1x Flexible tripod mount 1x Suction cup mount Downloads Datasheet User Guide Quick Start Guide SDR# User Guide Dipole Antenna Guide

Easy and Affordable Digital Signal Processing The aim of this book is to teach the basic principles of Digital Signal Processing (DSP) and to introduce it from a practical point of view using the bare minimum of mathematics. Only the basic level of discrete-time systems theory is given, sufficient to implement DSP applications in real time. The practical implementations are described in real time using the highly popular ESP32 DevKitC microcontroller development board. With the low cost and extremely popular ESP32 microcontroller, you should be able to design elementary DSP projects with sampling frequencies within the audio range. All programming is done using the popular Arduino IDE in conjunction with the C language compiler. After laying a solid foundation of DSP theory and pertinent discussions on the main DSP software tools on the market, the book presents the following audio-based sound and DSP projects: Using an I²S-based digital microphone to capture audio sound Using an I²S-based class-D audio amplifier and speaker Playing MP3 music stored on an SD card through an I²S-based amplifier and speaker Playing MP3 music files stored in ESP32 flash memory through an I²S-based amplifier and speaker Mono and stereo Internet radio with I²S-based amplifiers and speakers Text-to-speech output with an I²S-based amplifier and speaker Using the volume control in I²S-based amplifier and speaker systems A speaking event counter with an I²S-based amplifier and speaker An adjustable sinewave generator with I²S-based amplifier and speaker Using the Pmod I²S2 24-bit fast ADC/DAC module Digital low-pass and band-pass real-time FIR filter design with external and internal A/D and D/A conversion Digital low-pass and band-pass real-time IIR filter design with external and internal A/D and D/A conversion Fast Fourier Transforms (FFT)

Designed for overclockers and other power users, this fan keeps your Raspberry Pi 4 at a comfortable operating temperature even under heavy load. The temperature-controlled fan delivers up to 1.4 CFM of airflow over the processor, memory, and power management IC. The bundled heatsink (18 x 8 x 10 mm) with self-adhesive pad improves heat transfer from the processor. The Raspberry Pi 4 Case Fan works with Raspberry Pi 4 and the official Raspberry Pi 4 case.
